The reusable cooling pad for targeted pain relief in the lower back area. Ideal for alleviating swelling, inflammation, headaches, fever, sprains, etc., or for recovery after physical activities. Application: to be placed in the freezer. Relieves pain, muscle tension, and menstrual discomfort – convenient switching between warm and cold cycles. Long-lasting: provides prolonged cooling and deep muscle relaxation. Instructions: Allow the pad to cool completely after use. Directly placing a warm pad in the freezer can damage the gel/clay material and shorten the product's lifespan. To avoid moisture buildup or freezer burn, place the pad in a freezer-safe bag. Then freeze it or store it in the freezer for at least 2 hours or overnight for optimal results.
